2 Claims.

My invention relates to bags, and has special reference to multi-wallbags that are particularly adapted for cement and other weightysubstances.

i One of the objects of the invention is to provide a novel and improvedbag of this character.

'Another of the objects of the invention is to provide a multi-wall bagof the character indicated having at least one of its ends closed by asatchel type closure of novel and improved construction.

Referring to the drawing,

Figure 1 is a longitudinal sectional view, partly diagrammatical, of abag embodying the fea- 16 tures of my invention in their preferred form,the section being taken substantialy on the line 1-1 of Fig. 2; and

' Fig. 2 is a sectional view, taken on the line 2-2 of Fig. 1.

The bag illustrated in the drawing is of the type of the one describedand claimed in my pending application Ser. No. 274,330, filed May 1,1928, entitled Sacks with automatic closing means. The bag is formedfrom a multi-wall bag tube which has been flattened. At least one end ofthe tube is folded to provide asatchel-like bottom.

This satchel bottom has side flaps 1 and 2, a

- reinforcing strip 3, and end flaps 4 which are preferably providedwith inwardly projecting tongues 5 of corrugated or crinkled paper.-

In one form of bag illustrated in said pending application, the sideflaps 1 and 2 have their end portions arranged in overlapping relation.

Also in the bag shown in said pending application the reinforcing stripis substantially twice the length of the side flaps and is folded overthe under and upper sides of the side flaps.

In accordance with the present invention. in

its preferred form, the side flaps have their edges arranged in edge toedge relation and substantially in contact.

Also, in accordance with the present invention, the reinforcing strip 3is preferably substantially three times the length of the side flaps.The portion of this strip 3 intermediate its ends extends over the underside of the side flaps and its projecting end portions are folded downover the outer side of the side flaps, said end portions being arrangedin overlapping relation. The reinforcing strip is of substantially thecombined width of the side flaps so as to extend over substantially theentire area thereof.

Preferably, also, said reinforcing strip is pasted New York, N. Y.

areas of the upper and lower sides of the side 6 flaps, said side flapsbeing arranged in edge to edge relation as described. Also, by theprovision of the overlapping portions of the reinforcing strip whichextend over the top side of the side flaps, the side flaps are firmlyand securely held in position. As the reinforcing strip is bent overboth ends of the side flaps, said ends are effectively reinforced, andas these end portions together with the end flaps 4 provide valves inopposite ends of the satchel bottom, reinforcements at this point are ofconsiderable practical importance.

,While this method of reinforcement is particularly adapted where valvesare employed in both ends of the satchel bottom, it will be apparentthat it is also well adapted where a valve is provided in but one end ofthe satchel bottom, and also where the satchel bottom is employed on theunvalved end of the bag.

It will also be apparent to those skilled inthe .art that my inventionpermits various modifications without departing from the spirit thereofor the scope of the appended claims.

What I claim is:

1. In a multi-ply bag of the class described having a satchel type end,the improvement which comprises a reinforcing strip having a portionintermediate its ends extending over the under side of the side flaps ofthe satchel end, and both of the projecting ends thereof extending overthe outer side of the side flaps and arranged in overlapping relation,said overlapping portions of the reinforcing strip being securedtogether and extending substantially the length of the side flaps.

2. In a multi-ply bag of the class described having a satchel type end,the improvement which comprises a reinforcing strip having a portionintermediate its ends extending over the under side of the side flaps ofthe satchel end, and both of the projecting ends thereof extending overthe outer side of the side flaps and arranged in overlapping relation,said overlapping portions of the reinforcing strip being securedtogether and extending substantially the length and width of the sideflaps.
